Application filed June 2%, 1916.

T 0 (all whom it may concern.

Be it known that I, CHARLES W. JEAN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Copying- Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to copying machines and more particularly to apower driven machine having controlling means embodied therein, forimparting intermittent movement to certain of the elements thereof.

It has for an object to provide an improved type of copying machine inwhich a web of paper to receive an impression thereon is fed through themachine intermittently, and said web is moistened to receive theimpression, after which it passes about a drying roller and then througha cutting mechanism by 'which uniform lengths may be cut from saidwebbing.

v A further object of this invention is the provision of means forvarying the lengths of intermittent movement of the web through themachine.

A further object of this invention is the provision of improvedmeans forcutting and perforating sections of the webbing after the impression hasbeen made thereon.

A further object is the provision of improved means for adjusting theseveral rollers relatively to permit quick release of the com ressionbetween said rollers with each other.

.A further object. of this invention is the provision of an improvedform of fountain for moistening the webbing before it is fed between theimpression rollers.

A further object of this invention is the provision of a pair of rollersadjustablv carried by the frame with respect to a heating roller as tocause the moistened web to contact with said heated roller, where it isretained in a stretched condition during the drying process.

Further objects will be apparent from the following specification,appended claims and drawings, in which,

In copying machines of this character. where a letter printed withcopying ink is passed through a pair of impression rollers together witha moistened web, provision has not been made heretofore to treat saidweb after having received the impression thereon, so as to discharge theprinted co y of the letter from the machine in completed form, sofeatures have been embodied in this machine about to be described,wherein the moistened web, after having received the impression thereonis passed about. a, heated roller in a stretched state, so that as saidwebbing is dried, it is maintained in a stretching state to cause it toremain perfectly fiat and from the drying roller. it is fed throughfeeding rollers which maintain the desired tension on said webbing andthen this web is passed through a perforator and cutter which isoperated in timed relation with respect to the movement of said web asto cause uniform lengths or sheets to be severed from the end of thewebbing which when delivered from the machine are ready for filing.

Referring to the drawings in which the several features of this type ofmachine are clearly shown, 10 indicates a standard or base whichsupports a frame comprising the. side walls'll and 12 and bottom member13, The side walls 11 and 12 have rearwardly extending arms 14 which arenotched as at 15 to receive a shaft 16 on which a roll of webbing 17'may be placed. The shaft 16 has the adjustable collars 18 thereon,whichreceive the compression springs '19 and bear against cones 20 torestrict the free rotation of the roll of webbing 17 as the web 21 isdrawn therethrongh. The web 21 passes over a guide roller 22 carried inbearings in the walls of a well 23, with which the fountain 24 is formedintegrally, so that said well and fountain may be removed from the framefor refilling. The fountain 24 has a depending lip 25 which regulatesthe amount of water confined in the well 23 and the well and thefountain may be supported by brackets 26 which are secured to the sides11 and 12. The web then passes partly about a roller 27 which is carriedin the arms 28 pivoted as at 29 to the frames 11 and 12, so that thisroller may be swung to the position shown in dotted lines in Fig. 1 ofthe drawings, when the machine is not in use or when the web. is beingthreaded through the machine. The web then passes between the rollers 30and 31 of which the roller 31 is adjustable relatively to the roller 30to enable the desired amount of moisture being removed from the webbing21 and the webbing follows the rollers 30 about a portion' of itscircumference where the webbing is exposed to the face of a letter to becopied which is fed under the roller After the webbing has received theimpression from the letter to be copied by passing between the rollers30 and 32, it is fed over a guide roller 33 and then downwardly about anad- V justable roller 34. where its course is directed about thecircumference of the heated drying roller 35 and then about a secondadjustable roller 36 to the feeding rollers 37 and 38, from where itpasses through a cutting mechanism, where the individual sheets areformed of predetermined lengths.

The rollers 31 and 32 are carried upon the shafts 3!) and 40 which arejournaled in the movable bearings 41 and 42 respectively. and thesebearings receive contact from adjustable screws 43 and 44 which passthrough the pivoted supporting members 45 and 46 respectively. Themembers 45 and 46 have their free ends notched as at 47 and 48, whereheads 49 of the locking members 50 engage and these locking members arecarried by the shafts 51 and 52 respectively, having support upon theeccentrics 53 formed on said shafts so that when said shafts arepartially rotated as by the handles 54 and'55, the locking members 50cause the members 45 and 46 to vary the compression between the rollers30, 31 and 32 as the case may be.

4.3 and 44 to establish a relatively fixed relation and then the otherlocking means so provided may be used or released as desired, whenaltering the former adjustment.

The rollers 34- and 36 are carried by the arms 56 and 57, of which thearms at one end of the roller are provided with-the meshing gears 58 and59 to cause the rollers 34 and 36 to move proportionately. The arms 56and 57 are pivoted upon studs 60 carried by the ends of the frame 11 and12 and the gear 59 meshes with a pinion 61. carried by the shaft 62, towhich the crank pulleys therein,

It. is apparent that the desired tldJlIStIl'lOntis had by the screws 63is attached and this crank has a handle 64 formed thereon, as well as alocking pin 65 movably carried therein, so that as said handle is swungto either of its positions about the are 66, the pin 65 will lock ineither of the recesses 67 and 68.

The roller 35 is rotatably carried upon a fixed shaft 69 and this shaftis 'of tubular formation to admit electric wires passing to the interiorof said roller and to an electric heater contained therein, so that saidroller may have its circumference heated to the desired temperature fordrying the paper as it passes about said roller.

The feeding rollers 37 and 38 are frictionally driven at such speeds asto maintain the desired tension on the web as it passes from the roller36 and the roller 37 is carried by a shaft 70 which is journaled in thebearings 71 formed in the ends of the frames 11 and 12, while the roller38 has bearings 71 formed in the ends thereof, which are carried by ashaft 72 having an eccentric extension 73 therethrough, to pass throughthe ends 11 and 12 where one of said extensions receives the handle 74.It is apparent that rotation of the shaft 72 causes the rollers 37 and38 to bind against each other to a more or degree.

To establish the desired movement of the several rollers with respect toeach other. gears are formed on the ends of said rollers which intermeshand said gears are identified as follows: The shaft of the roller 30supports a gear 75 which meshes with a gear 76 secured to the shaft 39and a gear 77 secured to the shaft 40 and the rollers 37 and 38 havegears 7 8 and 7 9 attached thereto. to establish uniform rotationthereof.

A motor 119 is secured to the bottom member 13 and this motor has a conepulley 120 on the shaft thereof, about one of the passes the belt 121which also passes about one of the pulleys formed in the cone pulley 122on the stub shaft 123 to drive a spur gear 124 attached to said pulley.The gear 124 drives a corresponding gear 125 on the shaft126 and thisshaft is journaled in bearings 127 and 128 formed in the frame 129. Thebearing 127 hasa standard 130 rising therefrom to support the stub shaft123. A worm 131 is secured to the shaft 126 and this Worm drives theworm gear 132 which is attached to the shaft 116 journaled in hearingsin the standards 133. The shaft 116 termittent pinion 134 and also thecam 115 above described. The intermittent pinion 134 meshes with acorresponding gear 135 secured to the shaft 136 which is journaled inbearings in the standards 137 and the pinion has the curved portion' 138formed thereon which has a sliding engagement with either of thecorresponding portions 139 formed on the gear 135 so that as thesupports the inpinion 134 is continuously rotated, the gear 135 has twopositions in which its movement is intermittent. The shaft 136 alsosupports the gears 140 and 141 which mesh with pinions 142 and 143loosely mounted upon a shaft 144, on which a clutch member 145 isslidably mounted, but has engagement therewith as to cause the clutchmember to impart motion to said shaft as the clutch member is throwninto engagement with either of the clutch faces 146 or 147 formed on thehubs of the gears 142 and 143. The

shaft 144 is journaled in the bearings in the standards 148 and thisshaft supports a pulley 149 and a sprocket wheel 150. The pulley 149receives a belt 151 which may be crossed and also passes about a pulley152 secured to the shaft of the roller 37. The sprocket 150 receives achain 153 which passes over an idler 154 journaled on the stud 155carried by the side 12 of the frame and said chain passes about asprocket 156 formed on the shaft of the roller 30.

It is thought that the operation of this copying machine is apparent inview of the foregoing, but the following is a brief description of theoperation and use of this type of machine. \Vhen it is desired to usethemachine, the electric switches 172 and 173 may be thrown as tocomplete the circuit respectively through the heating element in thedrying roller 35 and through the motor 119 at which time the motor isstarted, the drying roller is heated. The arms 28 which support theroller 27 may be swung to the position shown in dotted lines in Fig. 1and the handles 64 may be swung to raise the arms 56 and 57 when the web21 may be threaded between the rolls 30, 31 and 32, over the roller 33and then pass between the rollers 37 and 38. Then the bail comprisingthe arms 28 and roller 27 may be swung forwardly as to immerse thatportion of the web passing thereunder in the moistening liquid in thewell 23 and the screws 43 will then be adjusted to cause the web passingbetween the rollers 30 and 31 to possess the desired amount of moistureto receive the copy. Then the roller 32 is adjusted to have the desiredbearing relation upon the letter to be copied and the web as it passesthrough the rollers 30 and 32 as by the adjusting screws 44. The letterto be copied is then fed between the rollers 30 and 32 which, as theyare rotated. cause the copy to be formed on the web 21 and after passingbetween these rollers, the letter may be collected in the tray 174.while the web is directed downwardly about the roller 34, which willhave been swung to one of the lower positions depending upon the lengthof the letter to be copied. After passing the roller 34, it partlysurrounds the drying roller apd then passes about the roller 36 to andbetween the feeding rollers 37 and 38 and then through the perforatingand cutting elements where the severed sheet may be collected in thebasket 175. The letter which may be fed into the machine may be fed fromthe table 176 upon which an ad j ustable guide 177 may be carried by theextensions 178 to permit the guide 177 being adjustable on said tablefor reasons which are apparent to users of this type of machine.

As it is commonly desired to copy letters or the like of both letter andlegal sizes, provision is made for maintaining a length of webbingbetween the impression rollers and the feeding rollers which will bemultiples of the length of the letter to be copied as for legal sizecopies, the rollers 34 and 36 are swung to the position indicated at Ain Fig. 1, when the length of the web is twice that of the legal sheet,but when it is desired to copy a letter of the standard letter size, thearms are swung to the position B in Fig. 1, when the length of the tapeis then three times that of the standard letter size, so it is .seenthat the severed sheet will always be of either of the standard lengths,being cut and perforated between the individual copies.

It is apparent that modifications may be made within the scope of theappended claims without departing from the spirit of this invention andno limitation is implied by the limited showing in the drawings whichare for illustrative purposes only.
